Create a working 3-D drawing of the catapult with Google SketchUp
Share their 3-D drawing with their classmates to gather suggestions for implementations
Standard - 3.1.8.A9
Formulate and revise explanations and models using logic and evidence.
Recognize and analyze alternative explanations and models.
Explain the importance of accuracy and precision in making valid measurements.
Checkpoints/Formative Assessments:
Four thumbnail sketches of catapult design
Decision matrix to choose best solution
Final 3-D drawing of chosen solution (catapult)
Instructional Strategies for ALL Learners:
Introduction to thumbnail sketches and examples
Worksheet explanation of four thumbnail sketches
Decision matrix lesson to evaluate final product (peer feedback of design)
Google SketchUp lesson on how to create working 3-D model
Build final catapult on Google SketchUp
How does this scaffolding activity relate to PBL unit?
This scaffolding activity relates to the PBL unit because students are actively engaged with developing a 3D model of a catapult design using a software program (Google SketchUp). Students are getting a chance to interact with each other in a group setting to model their chosen solution of a catapult design. This activity gives students the opportunity to use the design process, which is taught previously in the unit. Through creating the 3D model, students can problem solve and further develop social skills. Following this scaffolding activity, students will create a real-life catapult. This activity prepares students for building the final catapult. It also serves as a "real-world" example of using the design process to come up with a solution to a given problem.
Formulate and revise explanations and models using logic and evidence.
Recognize and analyze alternative explanations and models.
Explain the importance of accuracy and precision in making valid measurements.
Lesson Objective:
Students will be able to:
Create a working 3-D drawing of the catapult with Google SketchUp
Share their 3-D drawing with their classmates to gather suggestions for implementations
Materials/Resources Student computers Google SketchUp software
Steps & Procedures: 1. Ask students the question: What impact does a 3D drawing have on society? 2. Explain where 3D drawings are used in society (show examples of architecture work, CAD drawings, car parts) 3. Exploring Google SketchUp interface 4. Learning how to use SketchUp tools 5. Viewing the Quick Reference Card 6. Creating first 3D model in SketchUp 7. Saving and reopening a model 8. Begin catapult design in Google SketchUp 9. Peer Feedback of 3D catapult design 10. Modifications of 3D design 11. Display and Print Final 3D Catapult Design
